Description

자동차의 후드구조Hood structure of car

본 발명은 자동차의 후드(HOOD)구조에 관한 것으로, 더욱 상세히는 자동차의 후드를 외판은 철판으로 구성함과 동시에 내판프레임은 하니콤 복합재료를 사용하여 하니콤 구조로 구성하면서도 이들을 해밍에 의한 결합방법으로 결합하여서 경향화 및 구조단순화와 더불어 강도 및 강성을 증대시키도록 하는 새로운 개념의 자동차의 후드(HOOD)구조에 관한 것이다.The present invention relates to a hood (HOOD) structure of an automobile, and more particularly, the hood of the automobile is composed of a steel plate and the inner frame is made of a honeycomb structure using a honeycomb composite material, while combining them by a hamming The invention relates to a new concept of the hood of a vehicle (HOOD), which combines in a manner to increase the strength and stiffness as well as the tendency and structure simplification.

일반적으로 승용차의 후드는 철판(STEEL)의 재질로 이루어져 있음과 동시에 외판과 내판프레임으로 구성되어 있으며, 그 기능은 외판의 경우 형상을 구성하는 것이고 구체적인 강성은 내판프레임이 담당하게 되는 것이다.In general, the hood of a passenger car is made of a steel plate (STEEL) and at the same time composed of a shell and an inner frame, the function of the outer plate is to configure the shape and the specific rigidity is to be in charge of the inner frame.

그러나 내판과 외판이 만나 이루는 폐단면이 강성을 크게하여 전체적인 후드 강성을 강화시키는 구조이나, 이러한 구조는 중량이 크고 굽힘 강성 등 강성, 강도측면에서 불리한 단점을 지니고 있는 것이었다.However, the closed cross section between inner and outer shells increases the rigidity and strengthens the overall hood stiffness, but this structure has a disadvantage in terms of rigidity and strength, such as heavy weight and bending stiffness.

이러한 시험을 위하여 후드 덴트(HOOD DENT) 시험등이 있으며, 이것은 후드부분에 일정한 하중을 가하여 굽힘변형이 시험스펙을 만족하는지 여부를 파악하게 되는데, 이러한 구조에 있어서는 정면이나 옵셋(OFF-SET)충돌시 충돌에너지를 전혀 흡수하지 못하는 단점이 있는 것이었다.For this test, there is a hood dent test, which applies a constant load to the hood to determine whether the bending deformation satisfies the test specification. In such a structure, the frontal or offset collision There was a drawback of not absorbing collision energy at all.

본 발명은 상기와 같은 문제점을 고려하여 이루어진 것으로, 그 목적은 후드의 구조를 개선함으로써 경량화 및 구조단순화를 기하고, 원가절감 및 충돌특성을 향상시키도록 하는 것이고, 또한, 굽힘,비틀림 등에 따른 강성을 향상시키도록 하는 자동차의 후드(HOOD)구조를 제공함에 있다.The present invention has been made in consideration of the above problems, and its object is to improve the structure of the hood to reduce the weight and structure simplification, improve the cost reduction and the collision characteristics, and also the rigidity due to bending, torsion, etc. To provide a hood (HOOD) structure of the vehicle to improve the.

이러한 목적을 달성하기 위한 본 발명의 후드구조는 외판은 철판을 그대로 사용하되 내판프레임은 철판구조물을 사용하지 않고 하니콤으로 구성되는 경량복합제를 소재로 사용함으로써 달성되는 것이다.The hood structure of the present invention for achieving this purpose is achieved by using a light weight composite material consisting of honeycomb without using the iron plate structure as the inner plate frame, but the inner plate frame.

첨부도면의 도1 이하에서는 본 발명에 관한 구조를 상세히 보인 구성도로서, 이의 도면중 부호 10은 본 발명에 따른 후드의 외판을 표시하고 있음과 동시에 부호 20은 내판프레임을 표시하고 있다.1 of the accompanying drawings, the structure of the present invention is shown in detail. In the drawing, reference numeral 10 denotes an outer plate of the hood according to the present invention, and reference numeral 20 denotes an inner plate frame.

상기 외판(10)은 종래와 동일한 구성을 가지는 것이며, 이는 통상에서와 같이 철판을 절곡하여 전체적인 후드의 형상을 유지토로 구성되어 있다.The outer plate 10 has the same configuration as in the prior art, which is bent iron plate as usual, and is composed of a holding soil to maintain the shape of the overall hood.

또한, 상기 외판프레임(20)은 내부에 중공부(21)를 가지는 카본(22)으로서 고온진공성형으로 압착하여 성형되는 것이고, 이의 중공부(21)에는 하니콤(23)이 구비되어 있다.In addition, the outer frame 20 is a carbon 22 having a hollow portion 21 therein is formed by pressing by high temperature vacuum molding, the hollow portion 21 is provided with a honeycomb (23).

상기 카본(22)는 인장성능이 뛰어나며 하니콤(23)은 굽힘성능이 뛰어나므로 두가지를 합하면 두가지 장점을 모두 가진 강성,강도가 뛰어난 특성을 지니게 되는 것이다.The carbon 22 has excellent tensile performance, and the honeycomb 23 has excellent bending performance, so that the combination of the two will have characteristics of excellent rigidity and strength.

이때, 카본(22)과 하니콤(23)은 접착제에 의해 먼저 가접된 후 성형되는 것이고, 이의 가장자리에는 플랜지(24)를 갖추어 구성되는 것이며, 또한, 상기 내판프레임(20)의 상부에는 외판(10)이 덮어씌우는 식으로 체결되어 그 가장자리를 플랜지(24)에 절곡하여 해밍(HAMMING)으로 결합된다.In this case, the carbon 22 and the honeycomb 23 are first welded by an adhesive and then molded, and the edge of the inner plate 22 is formed by a flange 24. 10) is fastened in such a way that the edge is bent to the flange 24 and joined by a hamming.

또한, 상기 내판프레임(20)의 양측면에는 후드를 차체에 연결하기 위한 힌지가 체결되는데, 이는 첨부된 도면의 도5에서 보는 바와 같이 철판을 직각방향으로 절고하여서 된 힌지부재(25)를 내판프레임(20)의 소정위치에 삽입한 후 카본브라켓트(26)로 지지함과 동시에 접착제로 접합하여서 고온성형시켜 힌지부재(25)를 체결하게 되는 것이다.In addition, hinges for connecting the hood to the vehicle body are fastened to both side surfaces of the inner frame 20, which is a hinge member 25 formed by cutting the iron plate in a right angle as shown in FIG. 5 of the accompanying drawings. After the insertion into the predetermined position of the (20) is supported by the carbon bracket 26 and at the same time bonded by an adhesive to form a high temperature to fasten the hinge member (25).

따라서, 본 고안의 내판프레임(20)은 별도의 용접이나 보울팅 구조없이 고온진공성형으로 제조되는 것이며, 또한, 중앙부의 두께(L1) 보다는 가장자리의 두께(L2)가 얇은 즉, 중앙부에서 양측의 가장자리를 향해 점차적으로 두께가 얇은 형태로 구성되어 있는 것이다.Accordingly, the inner frame 20 of the present invention is manufactured by high temperature vacuum molding without a separate welding or bowling structure, and also has a thickness L2 of the edge rather than the thickness L1 of the center portion, that is, the two sides at the center portion. It is composed of gradually thinner thickness toward the edge.

이것은 중앙부의 경우 굽힘하중을 더 많이 받기 때문인 것으로, 즉, 하중이 F1 보다는 F2가 많이 받음으로써 두께로서 균형을 맞추도록 구성되어 있는 것이다.This is because the center part receives more bending load, that is, it is configured to balance the thickness by receiving more load F2 than F1.

계속해서, 이와 같이 구성되는 본 발명의 제조과정을 살펴보면, 이는 첨부도면의 도2 및 도3에서 보는 바와 같이 내판프레임(20)은 카본(22)과 경량복합소재로 이루어지는 하니콤(23)을 접착제로서 먼저 가접한 후 양측면에 힌지부재(25)를 삽입하여 카본브라켓트(26)로 지지한 다음 고온진공성형 방법으로써 단일체로 제조하게 되는 것이다.Subsequently, looking at the manufacturing process of the present invention configured as described above, which is shown in Figures 2 and 3 of the accompanying drawings, the inner frame 20 is made of a carbon 22 and a lightweight composite material honeycomb 23 First, the adhesive is welded, and then the hinge member 25 is inserted into both sides to be supported by the carbon bracket 26, and then manufactured into a single body by a high temperature vacuum molding method.

또한, 이와 같이 구성되는 상기 내판프레임(20)에 외판(10)을 조립시에는 상기 내판프레임(20)의 상부에 외판(10)을 덮어씌우는식으로 체결한다음 가장자리의 플랜지(24)를 이용하여 해밍방법으로서 양부재를 일체형으로 체결고정하게 되는 것이다.In addition, when assembling the outer plate 10 to the inner plate frame 20 is configured in such a way to cover the upper plate 10 to cover the upper portion of the inner plate frame 20 by using the flange 24 of the edge As a hamming method, both members are integrally fastened and fixed.

따라서, 이와 같이 구성되는 후드의 정면, 옵셋충돌시 충돌하중을 내판프레임(20)의 카본(22)과 하니콤(23)에서 대부분 흡수하게 되는 것이며, 즉, 본 발명에 따른 내판프레임(20)이 굽힘 및 비틀림 강성이 뛰어남에 이의 충돌하중을 효과적으로 흡수하게 되는 것이다.Therefore, the impact load during the collision of the front and offset of the hood configured as described above is mostly absorbed by the carbon 22 and the honeycomb 23 of the inner plate frame 20, that is, the inner plate frame 20 according to the present invention. This bending and torsional stiffness is excellent, so it effectively absorbs its impact load.

이상에서 상세히 설명한 바와 같이 본 발명에 따른 후드구조를 내열성 및 내구성이 강한 카본과 완충력이 뛰어난 하니콤구조로 개선함으로써 굽힘 및 비틀림 강성이 뛰어나 정면, 옵셋충돌시 그 충격하중을 보다 효과적으로 흡수하게 되는 효과를 가지게 되는 것이다.As described in detail above, the hood structure according to the present invention is improved to a heat resistant and durable carbon and a honeycomb structure having excellent buffering ability, so that the bending load and torsional rigidity are excellent, so that the impact load can be more effectively absorbed during frontal and offset collisions. Will have.

또한, 경량화를 실현할 수가 있음은 물론이고, 구조가 단순화되는 장점과 더불어 이에 따른 원가절감을 기할 수 있는 장점을 가지게되는 것이다.In addition, the light weight can be realized, and the structure is simplified, and the cost can be reduced accordingly.
